Can someone please direct me to a tutorial (for PSE10) that shows me how to use the cookie cutter tool? I'm trying to clip a picture into a circle using the tool... I've got it all clipped, but when I save the image it has the dreaded white background... I want to make it transparent. I'm not real proficient in PSE - I use gimp for most things, but I was trying to use a template I got for joining SG... and it requires a round photo...

Did you try the University for tutorials? I'm not that good with PSE myself. lately I've found that the blending mode "Multiply" will often take out the white background. I use it when I scan a photo and want to get rid of the white around an object.
